Abstract

The invention relates to a process for producing base material for the manufacture of plates, mats and mouldings from mixtures of ground rubber wastes with or without reinforcing inserts, masticating agents, natural rubber, accelerator system, zinc oxide and sulphur. The essential point of this invention is that 2 to 6% by weight, especially 2.5 to 4% by weight, of an aliphatic/aromatic soft resin are added as a viscous substance having a density of 0.8 to 1.2 g/cm<3> and a viscosity from 60 to 100 mPa.s at 80 DEG C to the rubber waste mixture, the mixing-in taking place on the roll (process variant I). A further process variant is described.
